jrcplnm. (ci. isi-'33) Thislinvention relatesitoac'cessories andzmeans employed for securely fastening complemental parts of a predeterminedlstructure. and; has more' particularref'erence t'oa simplebo'lt and'nut con:-

is characterized by an especially constructed nut fashioned to accommodate the complemental rctention means, whereby when the two parts are properly joined and assembled, rotation of the nut is prevented, whereby to permit the bolt to be tightened or loosened as the case may be through the instrumentality ofV an ordinary screw-driver.

It is a matter of common knowledge that the usual way of fastening a license plate to the holder is by way of an ordinary bolt and nut arrangement. Under ordinary conditions, the nut sometimes becomes loose and is lost, or the nut becomes rusted on the bolt and it is difficult to remove the bolt when it is desired to replace the tag unless this is accomplished through the use of a pair of pliers or a wrench in conjunction with a screw driver. My idea involves the use of simple and economical means cooperable with the nut to hold it against rotation whereby not only to prevent displacement of the nut but to allow the bolt to be applied and removed without neces- 40 sitating holding of the nut with a special tool.

Other features and advantages will become more readily apparent from the following description and drawings.

In the drawings:

Attention is rst invited more especially tothe structural features illustrated in Figures 1 to 7 inclusive. This is due to the fact that the invention may be carried out in several ways and I have decided to show two of the principal embodiments of the invention, that is, one form in Figures 8 and 9 and another form in the remaining gures. Fundamentally,.however, the idea is somewhat the same and has to do in particular with a satisfactory means for holding the nut against rotation so as to allow the bolt to be inserted and removed without requiring the use of a special tool.

In the drawings, in Figure 1, the support or hanger, sometimes referred to as the bracket, is denotedby the numeral I Il and is of any suitable construction to accommodate the conventional license plate or tag II. This plate as shown in Figures 6 is provided with the usual horizontal longitudinally elongated bolt accommodation slots I2. numeral I3 and is conventional and therefore The fastening bolt is denoted by the provided with the usual head I4 having a screwdriver kerf to accommodate a standard screwdriver (not shown). It is of course evident that the bracket IB as shown in Figure 2 is also provided with a slot I 2a which registers with the slot I2 to accommodate the bolt and nut fastening means. The nut, which is detailed in Figure 7, is a regular square nut and is indicated by the numeral I5. The principal structural distinction is that the nut is provided on opposite peripheral edges, that is, on Vits rim, with a pair of opposed guide notches I6. Theseare adapted for reception of a pair of companion spaced parallel retaining iingers `I'I carried on the back of a plate or other suitable carrier I8. The parts comprising the plate I8 and its retaining fingers may be conveniently referred to as an adapter as well as a nut lock. The style of the device shown in Figures 4 and 5, for example,

is applicable to the assemblage indicated in Figures l, 2, and 3. It is obvious, therefore, that the plate I8 ts against the license plate and that the fingers I'I extend through the registering slots and are fitted in the keeper notches or guides I6 in the nut. It follows, therefore, that with the parts thus assembled the nut is held against rotation, making it possible to insert or remove the bolt I3 in an expeditious and dependable manner.

In thea-rrangement shown in Figures 8 and 9, I also utilize a similar notched nut and adapter fixture. The adapter is here distinguished by the numeral I9 and comprises an L-shaped mern-V Y ber embodying locking fingers 2D and A vhas a` flange 2I at one end. 'I'he fingers are Vadapted to t into grooves 22 formed in opposed edges of Otherwise the nut is the same as that i l the nut. K shown in Figure 7 and denoted bythe numeral I5. The bolt is also the same, although in -this arrangement, I have merely added, as shown in Figures 8 and 9, a spring23 and a washer'Zd. These are incidental retention features. l

The gist of the invention is found in the us of a nut I5 having the notches I6 as well as the grooves 22, said nut being cooperable with the threaded stem of the bolt I3 and the features I6 and 22 being used depending on the nature of the adapter employed. When the adapter shown in Figure 4 is used, the fingers I1 extend into the notches I6. When the adapter I9 in Figure 9 is used, the ngers 2B extend into the grooves 22. In either instance, the principle is virtually the same.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description rin connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the eld of invention claimed may be resorted to in actual practice, if desired. Y

What is claimed is: A fastener 0f the class described, comprising a bolt and nut, said nut being provided in its marginal portions with a pair of opposed keeper notches for reception of an adapter, as well as in the adjacent rim portions with grooves intersecting said notches for receiving a second adapter, each adapter embodying fingers for reception in the notches and grooves.
